A wedge-shaped groove 16 is provided in the fixing seat 15. Through the arrangement of the fixing seat 15 and the wedge-shaped groove 16, the displacement plate 10 can be slidably adjusted on the front side of the C-shaped fixing plate 8. A plurality of slots 17 are provided on the front side of the limit seat 9, and a displacement slot 18 is provided in the limit seat 9. Two fixing knobs 19 are inserted and installed in the limit seat 9. The limit seat 9 is inserted and installed on the second connecting plate 13 in the slide groove 12 through the displacement slot 18, and the front side of the fixing knob 19 is threadedly connected to the corresponding screw hole 14. The limit seat 9 is inserted and installed in the slide groove 12 through the displacement slot 18, and the two fixing knobs 19 can be used to achieve extrusion displacement of the limit seat 9.

[0022] like Figure 3-Figure 4As shown, four sliders 20 are fixedly installed on the front side of the displacement plate 10, and two partitions 21 are also fixedly installed on the displacement plate 10 located between the four sliders 20. The center positions of the two partitions 21 are respectively provided with rotation holes 22. The displacement plate 10 is inserted and installed between the C-shaped fixing plate 8 and the two fixing seats 15, and the sliders 20 are slidably installed in the corresponding wedge-shaped grooves 16, and the screws on the rear side of the displacement plate 10 pass through the through grooves in the vertical part of the C-shaped fixing plate 8 and extend to the rear side of the C-shaped fixing plate 8. Through the arrangement of the displacement plate 10 and the sliders 20, the displacement plate 10 can cooperate with the first connecting plate 11 to drive the crossbeam 5 to move. Horizontal displacement adjustment, so as to further accurately adjust the positions of the two digital cameras 6, a connecting block 23 is fixedly installed on the rear side of the first connecting plate 11, and a plurality of latches 24 are fixedly installed on the outside of the connecting block 23, and the connecting block 23 is inserted between the two partitions 21, and a rotating shaft 25 is also inserted between the connecting block 23 and the two rotating holes 22. The latches 24 located on the rear side of the displacement plate 10 are clamped in the corresponding slots 17, and the first connecting plate 11 is rotatably installed between the two partitions 21 through the connecting block 23 and the rotating shaft 25.
